iOS实战演练之跳转界面时隐藏tabBar的方法

1.设置self.tabBarController.tabBar.hidden=YES;

2.如果在push跳转时需要隐藏tabBar，设置self.hidesBottomBarWhenPushed=YES;

self.hidesBottomBarWhenPushed=YES;
    ViewController *vc=[[ViewController alloc]init];
    [self.navigationController pushViewController:vc animated:YES];
    self.hidesBottomBarWhenPushed=NO;
           

       并在push后设置self.hidesBottomBarWhenPushed=NO;

       这样back回来的时候，tabBar会恢复正常显示
